EDMUND HANS, 0F MINNEABOLIS, MINNESOTA.

STRAINER FOB- GASOLENE-TANKS.

Specification of Letters Patent.

Be it known that I, EDM ND E. HANS, of

Minneapolis, Hennepin county, Minnesota,

have invented certain new and useful Improvements in Strainers forGasolene: Tanks, of which the following is a specification. l

' The object of my invention is to provide a device in connection with agasolene tankfor straining purposes to separate dirt and foreignmaterial therefrom before the oil enters the pipe leading to the enginecylinder. Screens and strainers of various kinds have heretofore beenprovided for this purpose, but they are all more or less objectionableas the foreign material will collect on and fill the meshes of thescreen itself, necessitating frequent attention to prevent seriousinterruption in the flow of the oil.

My invention has for its prima ry object, the separation of the dirt andforeign materlal from the gasolene largely by precipitation withoutdanger of the foreign material collecting and clogging the strainer orscreen itself.

My invention consists generally in a shield pipe or guard arranged toinclose'the inlet to the suction. pipe and having an open end projectinginto the cup whereto the suction pipe is attached. I

In the accompanying drawings, forming a part ofthis specification,Figure 1 is a side elevation of a gasolene tank embodying myinvention,.Fig. 2 is a vertical sectional view of the same,

In the drawing, 2 represents a tank having an opening 3 in its bottomand 4 a cup secured to the .bottom of, the tank around said opening andhaving a drain cock 5 through which the accumulation in the bottom ofthe cup may be drawn off. A suction pipe 6 has-a connection .7 with thecup 4 through the upper walls thereof. The inlet to the'suction pipe 6is preferably'located near the opening?) in *the bottom of the tank andto shield or guard this inlet opening, and to prevent dirt and foreignmaterial frombeing drawn into the suction pipe, .I provide a pipe 8having one end in- 'closing the inlet to the suction pipe and brazed orotherwise secured to the wall of the .cup 4 and preferably inclined tothe horizontal as indicated in Fig. 2 or 'ar-' ranged at an ,angle tothe axis of the pipe 6, if located as in saidfigure. The foreignmaterial in the gasolene' therefore settling on the rounded inclinedsurface of the pipe 8, will tend to slide off and be directed" therebyinto the bottom of the cup. The pipe 8 has an open end and is preferablyof greater diameter than the diameter of the inlet opening to the pipe6, so that the suction in said pipe 6 will not cause a strong draft atthe inlet of the pipe 8 but rather will allow the oil to move soslowlythat the force of gravity will overcome the tend-' ency of theparticles of dirt to enter the pipe 8 and will cause themto settle tothe bottom of the cup 4;. Within the pipe 8, I provide screens 9 and 10through which the gasolene passes; I have shown two of these screens buta greater or less number maybe provided as preferred and as the surfacesPatented Mar. 11,1913. Application filed April 1-1, 1910. Serial No.'5 54,891.

of the screens are inclined with respect to the axis of the suctionpipe, the foreign material coming in cont-act therewithwillhave atendency to slide off and drop to the bottom of the cup. The-screens areshownas located, one near the middle of the pipe 8 and the other at itsopen end. but they may be arranged in any other suit-able position intheshield pipe. i V Beneath the pipe 8, pan 11 secured by any suitablemeans in the cup and having a. hopper bottom with a discharge opening 12spaced from the bottom of the cup. This pan will prevent the foreignmaterial accumulating in the bottom of I prefer to provide a J the cupfrom being stirred up or shaken by i the motion of the car and drawn upto a point where they might 'tend' to lodge on the outer screen on theshield pipe. This shield i pipe may be made of any suitable length,and

its diameter with'respect t'o'the diameter of the suction pipe may bevaried to suitrthe, conditionsand to adaptit forthe enginewith;

which it is used.

In various ways, the details-of construetion herein maybe modifiedwithout; depart 1 ing' from theepirit ofmy invention:

I. claimas my invention:

1,.v Thejcombinatiomwv'ith a. gasolene tank, of a cup. inclosing anopening in the-bottom of saidtank and secured thereto and having adraincock, a suction pipe communicating with 'said'cup through the wallsthereofand near the opening in the bottomo'f said tank,

a- 'shield' pipe inclosing the inlet opening to. said suction pipe andhaving an open inner end and inclined Y the horizontal, and

ing' said opening and projecting into said cup and having imperforatewalls and an open inner end, said open end lying in a plane at an angleto the transverse axis oi said cup, said imperforate walls deflectingthe ascending and descending-particles of sediment, a screen disposed insaid opening, said cup having a wall below said guard operating todeflect the sediment toward the center of the cup away from the open endof said guard.v

. 3. The combination, with a tank having an opening in its bottom, of acup having an,

open top adapted to register with said opening and secured to said tank,said cup having a suction discharge opening in its side walls, a tubeopen at each end secured to the inner wall of said cup and encirclingsaid suction opening, said tube being downwardly inclined and projectingacross said cup,. the open end of said tube extending across the cup toa point near the opposite wall thereof from said suction opening ascreen provided in the open end of said tu e,

a second screen provided in said tube be- 4:. The combination, with atank havingan opening in its lower wall, of a cup surrounding saidopening, said cup having a discharge opening in its side walls, a guardsurrounding said opening and projecting into said cup and havingimperforate walls and an open inner end, said open end lying in a planeat an angle to the transverse axis of said cup, said imperforate wallsoperating to deflect the ascending and descending particles of sediment,a screen disposed in the open inner end of said guard, and meansarranged below said guard for deflecting the sediment toward the centerof said cup. In witness whereof, I have hereunto set my hand this 2ndday of April 1910.
